Sports stars and fans across the world are auctioning memorabilia to raise money for the victims of the terrorist attacks in the United States.

Tiger Woods, Andre Agassi and many others are helping to try and raise $100m in 100 days for disaster relief charities through the internet site 'Auction for America'.

New York mayor and self-proclaimed Yankees fan Rudolph Giuliani himself pledged a baseball autographed by Hall of Famer Yogi Berra.

"Sports memorabilia items have been incredibly hot over the
last few years," said Kevin Pursglove, senior director of
communications for E-bay.

Tiger's Pebble Beach flag has already raised $2,000

"We expect it will play a significant
role in our efforts to raise the $100m."

Through his foundation, Tiger Woods donated a framed autographed pin from the 2000 US
Open at Pebble Beach.

Bids for the flag and accompanying plaque had already
reached $10,000 on Tuesday with six days still to go.

Tennis is also playing its part - an autographed racket used by Agassi during the 2001
Australian Open has surpassed $2,000.

And an autographed Wimbledon programme from the final day of the 2000 Championships, signed 'Pete Sampras 13', signifying his record 13th Grand Slam triumph, drew a bid of $1,325.

The WTA Tour has authorised the sale of some 16
player-related items - a shirt worn and autographed by Anna
Kournikova has so far attracted the highest bid of $330.

After such horrible events last week, everyone is pulling
together to try to help

Similar items from Venus and Serena Williams and Jennifer
Capriati, a pair of Monica Seles' sneakers and a 1999 Wimbledon
order of play sheet signed by finalists Steffi Graf and
Davenport were also being auctioned.

"After such horrible events last week, everyone is pulling
together to try to help," Davenport said in a statement issued
by the WTA Tour.

"Even though this might not seem like much, in a time like
this every little bit can truly make a difference. This can
provide a way for tennis fans around the world to make an impact.

"On behalf of the entire Tour, our hearts go out to
everybody affected by this tragedy."

Many of the descriptions of items up for auction include
personal messages from ordinary fans donating their own
sports memorabilia.

One basketball fan offering his prized possession - a basketball
autographed by two-time NBA champion and LA Lakers star Shaquille O'Neal - wrote: "I would not part with this ball for any reason but this. Please open your wallets."

Meanwhile, the US PGA Tour has raised around $6m with "A Tribute to America" rally, with the help of players such as David Toms, Hal Sutton and Jesper Parnevik.

An estimated 6,000 people attended the event, which was held
at Lone Star Lil's Amphitheatre at Six Flags Fiesta Texas - next to the site of the Texas Open.
